Abstract (en)

[origin: EP0629740A1] The invention concerns a method, a device, and an arrangement of regulation in a paper machine for the control of the transverse profile or profiles of properties of the paper web (W) that is produced. Water is removed from the paper web (W) under compression between two forming wires (11,21) by making use of dewatering and/or forming ribs (14, 24,24A). The deflection of the dewatering and/or forming rib or ribs (14;24;24A) in the transverse direction of the web (W) is regulated. Thereby the retention profile of the paper web (W) in the cross direction is affected. By means of the regulation of the deflection of the dewatering and/or forming rib or ribs (14,24;24a), the transverse fibre-orientation profile and/or the filler profile of the paper web (W) is influenced through the control of the transverse retention profile of the web (W). <IMAGE>
